1'0 all whom, it may concern.-

Be it known that I, J OHN KAsrER HoL'r- MANN, a citizen of the UnitedStates of America, residing at St. Louis, State of Missouri, haveinvented new and useful Improvements in Vehicle-Wheels, of which thefollowing is a specification.

This invention relates to vehicle-wheels, and has for its objects toproduce a comparatively simple inexpensive device of this character inwhich the spokes may be readily removed, one in which the spokes will bemaintained firmly and securely in position, and one in which the spokeswill serve to hold the tire in position upon the rim.

\Vith these and other objects in view the invention comprises the novelfeatures ofconstruction and combination of parts more fully hereinafterdescribed.

In the accompanying drawings, Figure 1 is a side elevation of avehicle-wheel embodying the invention. Fig. 2 is a detail view, partlyin section and on an enlarged scale, the section being taken on the line2 2 of Fig. 1. Fig. 3 is an enlarged detail view in section of the outerend of one of the spokes.

Referring to the drawings, 1 designates the wheel, which as a wholecomprises a hub 2, a rim 3, and a tire 4, the rim being provided, asseen in Fig. 2, with side flanges 5, between which the tire is seated,while the hub 2 has a tapered central bore in which is arranged as usuala tapered metal 'box 6, having its ends in threaded engagement with thehub, it being apparent that owing to the box being tapered and the boreof the hub being correspondingly tapered the box may be introduced intoposition by entering its smaller end into the larger end of the bore andfinally rotated within the latter to properly engage the threads.

Extended radially between the hub and rim is a series of spokes 7, eachhaving at its hubengaging end a primary threaded engaging.

portion 8 and a secondary engaging portion 9, also threaded and ofsmaller diameter than the portion 8, while the outer end of each spokeis formed with an internally-threaded recess 10, designed to receive theexternallythreaded spindle ll of an adjustable sleeve or section 12,provided with an outer reduced portion or extension 13, adapted forengagement with the wheel-rim 3. The section 12 is preferably in theform of a tubular thimble, which slips upon the end of the spoke and hasformed centrally therein the threaded spindle or core 11, this thimblebeing telescopical upon the end of the spoke and adjustable lengthwiseof the latter through the medium of the threaded connection 10 11.

The wheel -rim 3 is provided at suitably' spaced intervals with openingsor perforations 14, designed in practice to register with sockets orseats 15, formed in the inner face of the tire 4, and the extensions 13are of such length as to extend through the openings 14 and be seatedwithin the sockets 15, thus to maintain the tire in position upon therim and prevent relative movement of the parts.

- In practice the spokes are first engaged with the hub 2 and the tire 4arranged upon the rim with sockets 15 in register with the openings 14,the outer ends of the spokes being thereafter engaged with the rim andtire by rotating the sleeves or thimbles 12 in the proper direction upontheir respective spokes to increase the length of the latter, asindicated by dotted lines in Fig. 3, whereupon the reduced extensions 13will enter through the openings 14in the rim and be seated within thetire-sockets 15.

From the foregoing it is apparent thatI produce a comparatively simpleinexpensive device in which the spokes may be readily seated in placeand engaged with the hub and rim and one wherein the tire will be heldin fixed position to prevent creeping upon the rim, it being understoodthat in attaining these ends various minor changes in the details hereinset forth may be resorted to without departing from the spirit of theinvention.

Having thus described the invention, what is claimed as new is In awheel, a hub, a rim provided with a perforation, a tire seated on therim and having a socket in register with said perforation, a spokehaving an axially-disposed internallythreaded recess, a tubular thimbleseated telescopically on the spoke and provided with an externallythreaded central core entered into and in threaded engagement with therecess, and a reduced extension provided in the thimble and designed toenter through the perforation in the rim and be seated in thetiresocket.

In testimony whereof I affix my signature in presence of two witnesses.
